This video demonstrates the hematoxylin and eosin (H&E) staining method to evaluate colon damage in a murine model of DSS-induced colitis — an inflammatory bowel disease. Upon isolating the colon from a DSS-treated mouse and obtaining sections of the tissue, H&E staining of the sections helps identify the inflammation-mediated tissue damage.

This video describes a protocol to detect radiation-induced DNA repair foci in the colon cancer cell lines using immunofluorescence staining. DNA repair proteins get activated at the DNA damage site; therefore, we can detect them using specific antibodies and visualize them under a fluorescence microscope.

Cartilage repair represents an unmet medical challenge and cell-based approaches to engineer human articular cartilage are a promising solution. Here, we describe three-dimensional (3D) biomimetic hydrogels as an ideal tool for the expansion and maturation of human articular chondrocytes.
FAQs
These approaches examine different consequences of cartilage injury. Imaging helps identify visible structural abnormalities, histological analysis reveals changes in tissue composition and organization, and mechanical testing evaluates load-bearing performance. Considering the results together provides a broader picture than relying on one measurement, allowing researchers to relate tissue appearance and microscopic structure to functional impairment.
Assessment can distinguish surface defects, altered tissue composition, disrupted organization, and reduced load-bearing performance. These features represent different aspects of cartilage quality rather than interchangeable findings. Examining them separately helps researchers determine whether an experimental condition primarily affects the tissue surface, its internal structure, its composition, or its ability to withstand mechanical demands.
Standardized assessment makes measurements more consistent across samples, disease models, and treatment groups. Consistent evaluation helps researchers interpret whether observed differences reflect disease progression, tissue repair, or variation in measurement. This is especially important when comparing therapeutic strategies, because structural improvement and restoration of function may not occur to the same extent.
A basic workflow combines structural imaging, histological analysis, and mechanical testing, with each method selected to address a different assessment goal. Researchers can examine surface defects and tissue organization, evaluate composition and microscopic changes, then measure load-bearing performance. The resulting measurements can be compared across experimental groups or time points to characterize tissue quality.
Researchers apply these measurements to cartilage injury models, tissue-engineered constructs, and osteoarthritis studies. In injury models, the methods characterize tissue damage; in engineered constructs, they help evaluate tissue quality; and in osteoarthritis research, they support comparisons of degeneration. The same combination of structural, cellular, and functional information can therefore serve different experimental contexts.
Treatment evaluation requires examining whether improvements occur across relevant dimensions of tissue quality. Imaging and histology can indicate better structural organization or composition, while mechanical testing can show whether load-bearing performance improves. Comparing treated and untreated samples with standardized measurements helps determine whether a strategy restores cartilage structure, function, or both.
